Molex NeoPress High-Speed Mezzanine Connection System

The modular NeoPress high-speed mezzanine system enables design flexibility on space-contrained PCBs with tunable differential pairs, low stack heights and compliant-pin terminations while offering data rates up to 28 Gbps.
As evolving telecommunication, industrial automation and medical applications demand higher speeds and smaller form factors, designers need to maximise PCB real estate without sacrificing performance. The NeoPress high-speed mezzanine system’s modular design achieves both high- and low-speed signals at 28 Gbps with tunable differential pairs (between 85 or 100 Ohms). Designers need only one connector for different speeds; therefore, they create space savings on the PCB.
SMT connectors are permanently affixed, making it virtually impossible to reuse PCBs. Also, when an SMT termination fails, attempting to rework it creates a short. Even though PCBs are expensive and being able to reuse them would create a cost savings, designers are reluctant to use press-fit mezzanine connectors because they typically offer lower signal integrity than SMT. NeoPress high-speed mezzanine system has been engineered to provide compliant-pin termination while minimising near-end and far-end crosstalk to match the signal integrity of NeoScale™ SMT connectors. The compliant pin enables designers to rework the board when necessary and maximise its use without having to sacrifice signal integrity.
